Lake Tahoe Casserole–slow cooker breakfast casserole with Italian sausage, eggs, cheese, bread, mushrooms and tomatoes.

Lake Tahoe Casserole
If you’re looking for a yummy brunch casserole or if you like eating breakfast for dinner this easy slow cooker breakfast casserole is for you. It’s got lots of flavor from the Italian sausage and I loved the addition of tomatoes and mushrooms for some freshness. If you’d rather, you can bake this in the oven in a 9×13 inch pan at 350 degrees for one hour. Another option is to do the prep the night before, refrigerate overnight and bake in the morning.
This recipe has been adapted from Tahoe Brunch Casserole on Kristin Andrus.
Ingredients/Substitution Ideas
- Ground Italian sausage–I used mild
- Onion–yellow, white
- Mushrooms

Steps
Heat a pan over medium high heat. Brown the sausage, onion and mushrooms for about 5 minutes. Transfer to the slow cooker. (My slow cooker has a stovetop function so I do this step in my slow cooker).

Stir in the bread cubes.

In a bowl whisk together the eggs, milk, mustard, nutmeg, parsley, salt and pepper. Pour the mixture into the slow cooker.

Add in the shredded cheese and stir.

Cover and cook on high for 2 ½-3 hours. Sprinkle on the tomato and cook for another 30 minutes.

Serve and enjoy.
